Description

Technical Field

[0001] This utility model relates to the field of aquaculture facilities technology, and in particular to a gas purification device and aquaculture system. Background Technology

[0002] Currently, large-scale livestock farming technology has matured. For livestock such as chickens, ducks, and rabbits, breeding systems are typically used. Because it is difficult to clean up excrement immediately after it is discharged, and frequent cleaning can easily lead to illness and anxiety in livestock, affecting their appetite, odors are inevitable in breeding systems. In this situation, effective ventilation helps to remove odors, while also preventing the spread of bacteria and pathogens to some extent, and regulating temperature to provide a better growing environment for the livestock.

[0003] However, simple ventilation is insufficient to meet air cleanliness requirements. Disinfection and purification of the air entering the aquaculture system are often necessary. Furthermore, when there are many aquaculture systems concentrated in one area, exhaust air also needs to be disinfected to ensure relatively clean intake air. Currently, disinfection and purification measures primarily involve installing ultraviolet lamps at the air inlet and outlet, and ozone disinfection of the exhaust air, but the actual disinfection effect is still not ideal. Utility Model Content

[0004] The purpose of this invention is to provide a gas purification device and aquaculture system with good air purification effect.

[0005] To achieve the above objectives, this utility model discloses a gas purification device, which includes:

[0006] The pipeline includes a first air outlet, a second air outlet, a first exhaust outlet, a second exhaust outlet, several first guide plates, and several second guide plates. The first air outlet is one opening of the pipeline, and the second air outlet is the other opening of the pipeline. Both the first and second exhaust outlets are located in the middle section of the pipeline, and each has a first opening / closing door. The first guide plates are positioned between the first air outlet and the first exhaust outlet, staggered and spaced within the pipeline, and cooperate with the inner wall of the pipeline to form a first baffle duct. One end of the first baffle duct is connected to the first air outlet, and the other end is positioned directly opposite the first exhaust outlet. The second guide plates are positioned between the second air outlet and the second exhaust outlet, staggered and spaced within the pipeline, and cooperate with the inner wall of the pipeline to form a second baffle duct. One end of the second baffle duct is connected to the second air outlet, and the other end is positioned directly opposite the second exhaust outlet.

[0007] Several ultraviolet lamps are installed in the duct. At least one ultraviolet lamp is installed between the first air outlet and the first baffle duct. At least one ultraviolet lamp is installed at the end of the first baffle duct near the first exhaust outlet. At least one ultraviolet lamp is installed between the second air outlet and the second baffle duct. At least one ultraviolet lamp is installed at the end of the second baffle duct near the second exhaust outlet.

[0008] There are at least two ozone supply points, with at least one ozone supply point in the first baffle duct and at least one ozone supply point in the second baffle duct.

[0009] With the above settings, in cooling mode, the gas entering the duct from the first and second air inlets is first irradiated with ultraviolet light to remove harmful microorganisms. The first and second baffle ducts extend the gas flow path, allowing the gas to remain in the duct for a longer time, resulting in more thorough mixing of ozone and gas. This more effectively removes ammonia, hydrogen sulfide, and other components from the gas, leading to better air purification. Additionally, ultraviolet lamps are installed at the ends of the first and second baffle ducts near the first exhaust vent to decompose any remaining ozone, ensuring that the ozone content in the gas discharged from the first and second exhaust vents meets standards. In insulation mode, the first and second exhaust vents are closed, with the second vent acting as an air inlet and the first as an air outlet, or their roles are reversed. This allows polluted gas to undergo multiple ultraviolet disinfection and baffle ozone reactions before recirculation, minimizing heat loss and achieving both insulation and air purification.

[0010] Preferably, the system further includes at least two atomizers, with at least one atomizer installed in the first baffle duct and at least one atomizer installed in the second baffle duct. By installing atomizers, a liquid phase atmosphere can be created, which can not only absorb water-soluble gases such as ammonia, but also make the reaction between ozone and ammonia more effective (compared to a gas phase atmosphere). In addition, atomization can also effectively cool down the air and remove dust.

[0011] Preferably, the system also includes a water collection tank. Both the bottom of the first and second baffle ducts are provided with overflow holes, which connect to the water collection tank. The water collection tank is provided with a drain outlet. This configuration allows for the collection and discharge of the atomized condensate, preventing water accumulation in the pipes and the growth of bacteria.

[0012] Preferably, a portion of the first guide vane is a bent plate, and this portion of the first baffle is positioned near the first air outlet; another portion of the first guide vane is a flat plate, and this portion of the first baffle is positioned near the first exhaust outlet. Similarly, a portion of the second guide vane is a bent plate, and this portion of the second baffle is positioned near the second air outlet; another portion of the second guide vane is a flat plate, and this portion of the second baffle is positioned near the second exhaust outlet. By designing a portion of the guide vane as a bent plate, the gas flow path of the baffle duct can be further extended, while designing the baffles near the first and second exhaust outlets as flat plates can better guide the purified gas to the first and second exhaust outlets, facilitating exhaust.

[0013] Preferably, the duct is further provided with a fresh air inlet and a third exhaust air outlet. A fixed baffle is installed in the duct, and the fixed baffle is located near the second air outlet. The fresh air inlet is located on one side of the fixed baffle, and the third exhaust air outlet is located on the other side of the fixed baffle. A rotating baffle is provided at the end of the fixed baffle away from the first air outlet, and the rotating baffle can block the connection between the third exhaust air outlet and the second deflector duct. The fresh air inlet is provided with a fresh air grille for opening and closing, and the third exhaust air outlet is provided with an exhaust grille for opening and closing. An ultraviolet lamp is provided next to the third exhaust air outlet. After the above settings, in cooling mode, the rotating baffle is rotated flat, and it will not block the gas from entering from the second air outlet. At this time, the fresh air grille and the exhaust grille are closed to prevent untreated gas from flowing out. In insulation mode, the fresh air grille and exhaust grille open, and the rotating baffle stands upright. Simultaneously, the first air vent acts as an exhaust outlet, and the second air vent as an intake outlet. An exhaust fan draws air into the second air vent; some of the intake air is disinfected by ultraviolet light and then exhausted through the third exhaust outlet, while the remaining intake air is disinfected by ultraviolet light and ozone before flowing out through the first air vent. Furthermore, under negative pressure, fresh air can flow into the duct through the fresh air vent and be disinfected by ultraviolet light and ozone before flowing out through the first air vent. The fresh air grille and exhaust grille are similar to louvers and can be designed for electric or manual control of opening and closing.

[0014] This utility model also discloses a breeding system, which includes:

[0015] The breeding shed has a disinfection chamber and at least one air inlet on its top. The air inlet is connected to the interior of the breeding shed through the disinfection chamber. The disinfection chamber is equipped with at least one air intake disinfection device. The air inlet is equipped with a second door. The disinfection chamber is equipped with a cooling water curtain.

[0016] At least one of the above-mentioned gas purification devices is installed outside the breeding house, the first air vent and the second air vent are both connected to the interior of the breeding house, and both the first air vent and the second air vent are equipped with a fan.

[0017] In cooling mode, the air inlets are open, and outside air is cooled by the cooling water curtain before entering the disinfection chamber for sterilization, and then flows into the breeding system. Inside the breeding shed, air is pumped into the ductwork by a fan, sterilized, and then discharged from the first and second exhaust vents. In heat preservation mode, the air inlets are closed, and the air inside the breeding shed circulates through the ductwork, undergoing sterilization during the circulation process.

[0018] Preferably, the livestock shed is equipped with a collection trough and at least one manure trough, the manure trough being connected to the collection trough. A manure scraper and filling cart is installed in the manure trough for scraping manure from the trough into the collection trough and laying bedding material into the manure trough. The manure scraper and filling cart includes a cart body, a scraper, and a hopper. The hopper is mounted on the cart body, and the scraper is detachably connected to the front end of the cart body. The width of the scraper is adapted to the width of the manure trough. The hopper has a discharge port, the width of which is adapted to the width of the manure trough. This configuration allows for simultaneous manure scraping and bedding material laying, improving the efficiency of manure treatment.

[0019] Preferably, the vehicle body is provided with a plurality of pulleys evenly distributed on both sides, the pulleys contacting the walls and / or bottom of the manure trough; the livestock shed is also provided with at least one drive device for driving the manure scraper and filler vehicle. With this configuration, it is not necessary to configure a power source for each manure scraper and filler vehicle, which helps to reduce costs.

[0020] Preferably, the drive device includes at least one drive assembly and at least one cable drive assembly, with each drive assembly corresponding to at least one cable drive assembly for transmission; the cable drive assembly corresponds one-to-one with the manure scraping and filling vehicle, or two adjacent manure scraping and filling vehicles share one cable drive assembly, and the manure scraping and filling vehicle is connected to the cable drive assembly by a cable. This configuration of the drive device results in a simple structure and facilitates maintenance.

[0021] Preferably, the system further includes a biogas digester located near the livestock shed. The biogas digester includes a fermentation chamber, a gas storage chamber, and a discharge chamber. The bottoms of the fermentation chamber and the discharge chamber are connected. The gas storage chamber is located above the fermentation chamber and has a gas outlet pipe with a safety valve. The fermentation chamber has a feed inlet, a limiting device, a gate, a feed reflector, a feed ramp, an inoculum overflow weir, and an inoculum conveying pipe. The gate is used to open and close the feed inlet. The limiting device cooperates with the gate to limit movement and form a unidirectional flow structure. The flow direction of the unidirectional flow structure is from the outside of the fermentation chamber to the inside of the fermentation chamber. The feed reflector is located in the middle of the fermentation chamber. The feed ramp is located at the feed inlet of the fermentation chamber, and the bottom of the ramp points towards the feed reflector. The inoculum overflow weir is arranged around the upper end of the fermentation chamber. One end of the inoculum conveying pipe is connected to the overflow weir, and the other end is connected to the outside of the biogas digester. By setting up a biogas digester, collected manure and packing materials can be fermented and processed, thus utilizing waste. The safety valve can be a spring-loaded safety valve; when the internal gas pressure of the biogas digester exceeds a set value, the safety valve opens to release gas and prevent an explosion due to excessive pressure. The limit components and gate valve design ensure that, under normal conditions, the internal gas pressure of the biogas digester will not force the gate valve open. However, when feeding is needed, the gate valve can be opened by a pushing tool and the weight of the material, thus enabling feeding.

[0022] This utility model has the following beneficial effects:

[0023] This invention has two working modes: heat preservation mode and cooling mode. In cooling mode, the air inlet is opened, and outside air is cooled by the cooling water curtain before entering the disinfection chamber for sterilization. It then flows into the breeding system for further cooling and ventilation. The hot and polluted air inside the breeding shed is pumped into the pipes and discharged. The gas pumped into the pipes is first irradiated with ultraviolet light to remove harmful microorganisms. By setting up a first and second baffle duct, the gas flow path into the pipes is longer, allowing the gas to remain in the pipes for a longer time. This allows for more thorough mixing of ozone and gas, effectively removing components such as ammonia and hydrogen sulfide, resulting in better air purification. Furthermore, ultraviolet lamps are installed at the end of the first baffle duct near the first exhaust vent and at the end of the second baffle duct near the second exhaust vent to decompose any remaining ozone, ensuring that the ozone content of the gas discharged from the first and second exhaust vents meets the standards. In heat preservation mode, the air inlet is closed, and the first and second air outlets are closed. The air inside the breeding house is circulated through the pipes by the fan. During the circulation process, the air undergoes multiple ultraviolet disinfection and ozone deflection reactions, which can ensure that the air returning to the breeding house is clean and that the air temperature is reduced, thus achieving both heat preservation and air purification.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0044] like Figures 1-14 As shown, this utility model discloses a breeding system, which includes a breeding shed 10, at least one gas purification device 20, and a biogas digester 30. A disinfection chamber 11 and at least one air inlet 12 are provided on the top of the breeding shed 10. The air inlet 12 connects to the interior of the breeding shed 10 through the disinfection chamber 11. At least one air disinfection device 13, preferably an ultraviolet lamp, is provided in the disinfection chamber 11. Additionally, a second opening / closing door 14 is provided on the air inlet 12 to open and close the air inlet 12. A cooling water curtain 15 is provided inside the disinfection chamber 11 to cool the gas entering through the air inlet 12. Furthermore, a barrier net or grille can be installed at the air inlet 12 to prevent birds or rodents from entering.

[0045] The gas purification device 20 is installed outside the breeding shed 10. In this case, two sets of the gas purification device 20 are installed, located on both sides of the breeding shed 10 respectively. The gas purification device 20 includes a pipe 21, several ultraviolet lamps 22, at least two ozone supply points 23, and at least two atomizers 24. The pipe 21 is provided with a first air outlet 25, a second air outlet 26, a first exhaust air outlet 27, a second exhaust air outlet 28, a third exhaust air outlet 29, a fresh air inlet 2a, several first guide plates 2b, and several second guide plates 2c. The first air outlet 25 is one of the pipe openings of the pipe 21, and the second air outlet 26 is the other pipe opening of the pipe 21. Both the first air outlet 25 and the second air outlet 26 are connected to the interior of the breeding shed 10, and a fan is installed at both the first air outlet 25 and the second air outlet 26. The fan can be installed at the pipe opening of the pipe 21 or on the outer wall of the breeding shed 10. The first exhaust vent 27 and the second exhaust vent 28 are both located in the middle section of the duct 21. The first exhaust vent 27 and the second exhaust vent 28 are each equipped with a first opening and closing door 2d. The first exhaust vent 27 and the second exhaust vent 28 can be combined into one unit.

[0046] The first guide plate 2b is positioned between the first air outlet 25 and the first exhaust outlet 27. The first guide plate 2b is staggered and spaced within the pipe 21, and its interaction with the inner wall of the pipe 21 forms a first baffle duct 2e. One end of the first baffle duct 2e connects to the first air outlet 25, and the other end faces the first exhaust outlet 27. More specifically, the portion of the first guide plate 2b near the first air outlet 25 is a bent plate, while the other portion is a flat plate, with this portion positioned near the first exhaust outlet 27. This arrangement allows the front end of the first baffle duct 2e (the end near the first air outlet 25) to be more curved, facilitating the extension of the airflow path. The rear end of the first baffle duct 2e (the end near the first exhaust outlet 27) is relatively straight, facilitating the guidance of airflow to the first exhaust outlet 27 for discharge.

[0047] The second guide plate 2c is similarly configured to the first guide plate 2b. Specifically, the second guide plate 2c is positioned between the second air outlet 26 and the second exhaust outlet 28. The second guide plate 2c is staggered within the pipe 21, and its interaction with the inner wall of the pipe 21 forms a second baffle duct 2f. One end of the second baffle duct 2f connects to the second air outlet 26, and the other end faces the second exhaust outlet 28. The second guide plate 2c is a bent plate, with this portion positioned close to the second air outlet 26. Another portion of the second guide plate 2c is a flat plate, with this portion positioned close to the second exhaust outlet 28.

[0048] Both the fresh air inlet 2a and the third exhaust vent 29 are located near the second exhaust vent 26. A fixed baffle 2g is installed in the duct 21, and this fixed baffle 2g is located near the second exhaust vent 26. The fixed baffle 2g is placed horizontally, dividing the second exhaust vent 26 into upper and lower layers. The fresh air inlet 2a is located on one side (lower side) of the fixed baffle 2g, and the third exhaust vent 29 is located on the other side (upper side) of the fixed baffle 2g. A rotating baffle 2h is provided at the end of the fixed baffle 2g away from the first exhaust vent 25. When the rotating baffle 2h is upright, it can block the connection between the third exhaust vent 29 and the second deflector duct 2f. When the rotating baffle 2h is laid flat, it no longer blocks the connection. A fresh air grille 2i is provided on the fresh air inlet 2a to control its flow, and an exhaust grille 2j is provided on the third exhaust vent 29 to control its flow. The fresh air grille 2i and the exhaust grille 2j can be electrically or manually controlled louvers, or they can be set as baffle doors.

[0049] Ultraviolet lamps 22 are installed in duct 21. At least one ultraviolet lamp 22 is installed between the first air outlet 25 and the first deflector duct 2e. At least one ultraviolet lamp 22 is installed at the end (rear end) of the first deflector duct 2e near the first exhaust outlet 27. At least one ultraviolet lamp 22 is installed between the second air outlet 26 and the second deflector duct 2f. At least one ultraviolet lamp 22 is installed at the end (rear end) of the second deflector duct 2f near the second exhaust outlet 28. In addition, an ultraviolet lamp 22 is installed next to the third exhaust outlet 29. The ultraviolet lamp 22 is located on the upper layer of the baffle.

[0050] At least one ozone supply point 23 is provided at the front end of the first deflecting duct 2e, and at least one ozone supply point 23 is provided at the front end of the second deflecting duct 2f. The ozone supply point 23 can be an ozone generator or an ozone supply pipe 2k, which is connected to an external ozone supply source, preferably the latter.

[0051] At least one atomizer 24 is installed at the front end of the first deflecting air duct 2e, and this atomizer 24 is closer to the first air outlet 25 than the ozone supply point 23. At least one atomizer 24 is installed at the front end of the second deflecting air duct 2f, and this atomizer 24 is closer to the second air outlet 26 than the ozone supply point 23. A water supply pipe 2m is installed outside the pipe 21 to supply water to the atomizer 24. In order to discharge the atomized condensate from the pipe 21 and avoid the accumulation of liquid leading to bacterial growth, or even the backflow of liquid into the breeding shed 10, a water collection tank 2n is also installed at the bottom of the pipe 21. Overflow holes are provided at the bottom of both the first deflecting air duct 2e and the second deflecting air duct 2f. The overflow holes are connected to the water collection tank 2n. The water collection tank 2n is provided with a drain outlet. The drain pipe can be connected to the manure trough 17 of the breeding shed 10 or to the biogas digester 30 via a water pipe.

[0052] This utility model system has a cooling mode and a heat preservation mode. For example, the cooling mode is activated when the ambient temperature is ≥25℃, and the heat preservation mode is activated otherwise. In the cooling mode, the first opening and closing door 2d and the second opening and closing door 14 are opened, and external air enters the disinfection chamber 11 through the air inlet 12. When the external air enters, it is first cooled by the cooling water curtain 15, and then disinfected by the air intake disinfection device 13 before flowing into the breeding house 10. At the same time, the fan is started, and the air inside the breeding house 10 flows into the pipe 21 through the first air outlet 25 and the second air outlet 26. This part of the air is first disinfected by ultraviolet light, and then disinfected by water mist adsorption of water-soluble gases and ozone, before being discharged from the first exhaust outlet 27 and the second exhaust outlet 28, thereby completing the replacement and cooling of the air inside the breeding house 10. In addition, in the cooling mode, the fresh air outlet 2a and the third exhaust outlet 29 are closed, and the rotating baffle 2h is leveled to avoid interfering with the air intake.

[0053] In heat preservation mode, the first opening / closing door 2d and the second opening / closing door 14 are closed, the air inlet 12 no longer receives air, and the first exhaust vent 27 and the second exhaust vent 28 no longer exhaust air. The fresh air inlet 2a and the third exhaust vent 29 are opened, the second air inlet 26 becomes an air inlet under the action of the fan, and the first air inlet 25 becomes an air outlet. At the same time, the rotating baffle 2h is erected. Part of the air passing through the first air inlet 25 is discharged from the third exhaust vent 29 after ultraviolet disinfection, and the other part flows back to the breeding house 10 from the first air inlet 25 after passing through the second deflector duct 2f and the first deflector duct 2e. In addition, under the action of negative pressure, fresh air from outside can enter the pipe 21 from the fresh air inlet 2a, and flow into the breeding house 10 from the first air inlet 25 after passing through the second deflector duct 2f and the first deflector duct 2e.

[0054] To improve the treatment capacity of manure in the livestock shed 10, a collection trough 16 and at least one manure trough 17 are installed inside the livestock shed 10. In this case, four manure troughs 17 are installed, and all manure troughs 17 are connected to the collection trough 16. A manure scraper and filler cart 18 is installed in the manure trough 17. The manure scraper and filler cart 18 includes a cart body 19, a scraper shovel 1a, and a hopper 1b. The hopper 1b is installed on the cart body 19 and has a discharge port 1c for laying bedding material in the manure trough 17. The bedding material can be corn stalks, etc. The width of the discharge port 1c is adapted to the width of the manure trough 17. The scraper shovel 1a is detachably connected to the front end of the cart body 19 and is used to scrape the manure in the manure trough 17 to the collection trough 16. The width of the scraper shovel 1a is adapted to the width of the manure trough 17.

[0055] Several pulleys 1d are evenly arranged on both sides of the vehicle body 19. The pulleys 1d contact the walls and / or bottom of the manure trough 17, and the pulleys 1d are arranged to facilitate the smooth movement of the vehicle body 19. The vehicle body 19 is not powered; instead, a dedicated drive device is installed inside the livestock shed 10. Specifically, the drive device includes at least one drive component 1e and at least one cable transmission component 1f, with each drive component 1e corresponding to at least one cable transmission component 1f. The cable transmission component 1f corresponds one-to-one with the manure scraping and filling cart 18, or two adjacent manure scraping and filling carts 18 share one cable transmission component 1f. The manure scraping and filling cart 18 is connected to the cable of the cable transmission component 1f, and the vehicle body 19 moves back and forth in the manure trough 17 by controlling the forward and reverse rotation of the cable transmission component 1f. This drive device has a simple structure and is easy to maintain.

[0056] The biogas digester 30 is located near the livestock shed 10. Manure and bedding collected by the collection trough 16 are transported to the biogas digester 30, allowing the inlet of the biogas digester 30 to be directly connected to the collection trough 16 for convenient material transport. The biogas digester 30 includes a fermentation chamber 31, a gas storage chamber 32, and a discharge chamber 33. The fermentation chamber 31 and the discharge chamber 33 are connected at the bottom, and the top of the discharge chamber is the discharge outlet. The gas storage chamber 32 is located above the fermentation chamber 31 and has a gas outlet pipe 34. A safety valve 3c, such as a spring safety valve or other type of pressure relief valve, is installed on the gas storage chamber 32. The fermentation chamber 31 is equipped with a feed inlet 39, a limiting member 3a, a gate 3b, a feed reflector 35, a feed inclined plate 36, an inoculum overflow weir 37, and an inoculum conveying pipe 38. The gate 3b is used to open and close the feed inlet 39. The upper end of the gate 3b is hinged to the upper end of the feed inlet 39. The limiting member 3a is fixedly set on the side of the feed inlet 39 located outside the biogas digester. The limiting member 3a and the gate 3b limit each other and form a one-way conduction structure. The conduction direction of this one-way conduction structure is from the outside of the fermentation chamber 31 to the inside of the fermentation chamber 31. In this way, when feeding, the gate 3b can be pushed into the fermentation chamber 31 by the material (manure) or a pushing tool to open the feed inlet 39 for feeding. When not in the feeding state, the gate 3b closes the feed inlet 39 under its own weight. Moreover, when the gas pressure inside the biogas digester is greater than the external atmospheric pressure, the gate 3b is limited by the limiting member 3a and will not be pushed open, thus preventing gas leakage.

[0057] The feed reflector plate 35 is located in the middle of the fermentation chamber 31, and the feed ramp 36 is located at the feed inlet of the fermentation chamber 31, with the bottom of the ramp pointing towards the feed reflector plate 35. In this way, the waste introduced from the feed ramp 36 can be evenly distributed throughout the fermentation chamber 31 via the feed reflector plate 35. The inoculum overflow weir 37 is arranged around the upper end of the fermentation chamber 31. One end of the inoculum conveying pipe 38 is connected to the inoculum overflow weir 37, and the other end of the inoculum conveying pipe 38 is connected to the outside of the biogas digester 30. The inoculum liquid is introduced into the inoculum overflow weir 37 through the inoculum conveying pipe 38, and the inoculum liquid can flow into the fermentation chamber 31 relatively evenly.

[0058] During the fermentation process, biogas will be continuously produced, and the gas pressure and water pressure in the digester will also increase. Under the action of gas pressure and water pressure, the biogas liquid and biogas residue that have been fully fermented at the bottom of the fermentation chamber 31 will be pressed into the discharge chamber 33 to prevent the biogas digester 30 from exploding due to excessive pressure. At the same time, the purpose of automatic discharge is achieved, reducing energy consumption.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
